Returns the type that must be returned by the invocation handler of a dynamic proxy in order to have the dynamic proxy return the specified type (which is assumed to be a legal member type for an annotation).

 public boolean isInherited()

}

Returns true if this this annotation type is inherited.

 public Map memberDefaults()

}

Returns the default values for this annotation type (Member name -> default value mapping).

 public Map memberTypes() 
{
        return memberTypes;
}

Returns member types for this annotation type (member name -> type mapping).

 public Map members() 
{
        return members;
}

Returns members of this annotation type (member name -> associated Method object mapping).

 public RetentionPolicy retention() 
{
        return retention;
}

Returns the retention policy for this annotation type.
